CROSS REFERENCE TO RELATED APPLICATION

The present application claims priority to Korean Patent Application No.10-2021-0176212, filed Dec. 10, 2021, the entire contents of which isincorporated herein for all purposes by this reference.

BACKGROUND OF THE INVENTION Field of the Invention

The present invention relates to a mist sprayer, which sprays cosmeticsin the form of a spray and, more particularly, to a container housing ofthe mist sprayer with an improved structure to prevent the outflow ofstored cosmetics.

Description of the Related Art

Conventional mist sprayers have been introduced in Korean PatentPublication No. 10-2018-0051873, Korean Patent Publication No.10-2018-0097067, Korean Patent Registration No. 10-2152955 and etc. andare gradually widely used due to their advantage of being able to beused without a problem of nozzle clogging even when spraying a cosmeticfluid having a high viscosity.

However, depending on the type of cosmetic solution, the nozzle maystill be blocked by the cosmetic solution solidified by the suspendedparticles contained in the aqueous solution. As, in this case, the mistsprayer cannot be used as a whole and had to be disposed of according tothe above-described conventional technologies, a solution to thisproblem was required.

In order to solve such a conventional problem, the applicant proposed amist sprayer 1 as shown in FIG. 1 . It has an improved structure thatallows a nozzle 350 to be installed in a container housing 300detachably coupled to a main body housing 100. In the event of a failurein which the nozzle 350 is blocked, the container housing 300 may bereplaced with a new one like consumables to be mounted on the main bodyhousing 100. Therefore, it is possible to solve the problem of disposingof the entire mist sprayer 1.

With this improvement, as shown in FIGS. 1 and 2 , a vent hole 332 isformed in a sealing lid 330 to help the cosmetic liquid stored in astorage tank 320 to flow smoothly into a cosmetic liquid outflow pipe322.

However, since the mist sprayer 1 is frequently carried by the user in abag or the like, it may be possible to respond to some extent by settingthe size of the vent hole 332 slightly smaller in consideration of caseswhere it is stored sideways or upside down.

However, in the case of an external impact, the outflow occurred throughthe vent hole 332, so a corresponding improvement was required.

SUMMARY OF THE INVENTION

Accordingly, the present disclosure has been made keeping in mind theabove problems occurring in the related art, and the objective of thepresent disclosure is to provide an improved container housing for amist sprayer to prevent the cosmetic liquid stored in the storage tankfrom leaking through the vent hole.

In order to achieve the above objective, the present disclosure providesa container housing for a mist sprayer, the container housing comprisinga storage tank formed in an inner space of a container wall to storecosmetic liquid, a cosmetic liquid outlet formed in the center of adepressed surface that forms a bottom of the storage tank, a sealing lidcoupled to an upper end of the container wall to cover the open upperend of the storage tank so as to be opened and closed, wherein thesealing lid comprises a cap receiving part formed by depression from thesurface of a cover plate, a leak storage space part formed by beingdepressed into a narrower inner diameter with a step as a boundary withthe cap receiving part, and a microtube formed to protrude toward thedepressed surface of the storage tank by being depressed from the bottomsurface of the leakage storage space, the container housing furthercomprising a sealing cap inserted into the cap receiving part andtightly coupled therein, the sealing cap having a fine vent pipecommunicating between the outside of the cover plate and the leakagestorage space part.

According to an aspect of the present disclosure, a protruding end ofthe microtube is located higher than the level of the cosmetic liquid ofa standard capacity of the storage tank whether the container housing isin an upright state or in an inverted state, and the microtube is alwayslocated higher than the level of the cosmetic liquid of the standardcapacity until the container housing in the upright state is tilted to ahorizontal lying state.

According to an aspect of the present disclosure, the sealing lid has alid wall formed to a certain depth along the edge, the protruding end ofthe microtube is formed to extend substantially to a lower end of thelid wall, and the level of the cosmetic liquid of the standard capacityis lower than the lid wall when the container housing is in the invertedstate.

According to an aspect of the present disclosure, the cosmetic liquid ofthe standard capacity is accommodated only in the storage tank and doesnot contact the lid wall when the container housing is in the uprightstate.

According to an aspect of the present disclosure, the sealing cap ismade of silicon.

According to the container housing for a mist sprayer according to thepresent invention as described above, although external air may flowinto the inner space of the storage tank through the fine vent pipe ofthe of the sealing cap, the leakage storage space part and themicrotube, the cosmetic liquid stored in the storage tank can be made tobe difficult to flow out through the microtube. Even if there is acosmetic liquid that passes through the microtube, it will only smear onthe bottom of the leakage storage space part so that it is verydifficult to flow out through the fine vent pipe of the sealing cap.Therefore, it is possible to substantially prevent the cosmetic liquidstored in the storage tank from leaking to the outside.

DETAILED DESCRIPTION OF THE INVENTION

As shown in FIGS. 3 and 4 , a container housing 400 according to theembodiment of the present invention includes a sealing cap 430. A coverplate 433 of the sealing lid 430 is recessed at the center of itssurface to form a cap receiving part 432. A silicone sealing cap 440 isinserted into the cap receiving part 432 and is closely coupled to eachother. A fine vent pipe 441 is vertically formed in the center of thesealing cap 440.

A leakage storage space part 435 is provided at a lower end of the capreceiving part 432 to be formed by being depressed into a narrower innerdiameter with a stepped part 434 as a boundary (see FIG. 5 ). Amicrotube 436 is further provided to be formed by being depressed from ahorizontal bottom surface 435 a of the leakage storage space part 435.

Referring to FIG. 5 , a lid wall 437 forming the edge of the sealing lid430 is formed to have a predetermined height up and down, that is, apredetermined depth (H) unlike the conventional technology (see 330 inFIG. 2 ). A protruding end 436 a forming the lower end of the microtube436 is extended to approximately coincide with the lower end line of thelid wall 437.

FIG. 6 illustrates a state in which the sealing lid 430 as describedabove is coupled to a storage tank 420. The storage tank 420 in whichthe cosmetic liquid is accommodated is defined by a container wall 410as an inner space thereof. A cosmetic liquid outlet (not shown in thedrawing, see 322 of FIG. 2 ) is formed at the center of a recessedsurface 421 forming an inclined bottom of the storage tank 420.

The sealing lid 430 is coupled to the upper end of the container wall410 to cover the open upper end of the storage tank 420 so as to beopened and closed.

FIG. 6 shows the container housing 400 in an upright state where thecosmetic liquid L is accommodated in the storage tank 420 to itsstandard capacity (ex. 7 cc). The volume of the storage tank 420 is setso that the cosmetic liquid L is sufficiently contained by forming itslevel M1 up to about half the height of the container wall 410.Accordingly, the protruding end 436 a of the microtube 436 of thesealing lid 430 is positioned higher than the level M1 of the cosmeticliquid L, so that it does not allow the cosmetic liquid L to contact orpermeate therein.

FIG. 7 shows the container housing 400 in an inverted state where thecosmetic liquid L accommodated to the standard capacity is containedonly in the sealing lid 430. That is, the water level M2 of the cosmeticliquid L forms a lower height than the lid wall 437. In this case, asthe protruding end 436 a of the microtube 436 is substantially on thesame height line as the lid wall 437, it is still located higher thanthe level M2 of the cosmetic liquid L. Therefore, it is possible toprevent the cosmetic liquid L from easily permeating.

FIG. 8 shows the container housing 400 in a horizontal lying state. Evenat this state, the protruding end 436 a of the microtube 436 is stillpositioned higher than the water level M3 of the cosmetic liquid Laccommodated to the standard capacity.

According to these principles, it can be seen that the protruding end436 a of the microtube 436 is always located higher than the level (seeM1, M3) of the cosmetic liquid L from the standing state of FIG. 6 tothe horizontal lying state of FIG. 8 .

In addition, even in the inverted state of FIG. 7 , since the cosmeticliquid L does not reach the protruding end 436 a of the microtube 436,it can be seen that the outflow through the microtube 436 will beextremely rare.

Moreover, even if the cosmetic liquid L in the state including any ofFIGS. 6 to 8 flows into the microtube 436 due to the external impact orothers, it is primarily deemed to be stained on the bottom surface 435 aof the leakage storage space part 435 connected at a right angle fromthe microtube 436, so it does not immediately leak outside.

Since the cosmetic liquid L flowing out to the leakage storage spacepart 435 will be only a small amount and this will mainly spread alongthe wall, it will be very difficult for the cosmetic liquid to passthrough the bottom surface 435 a which is perpendicular to themicrotubule 436, an inner wall surface 435 b which is perpendicular tothe bottom surface 435 a and reach the sealing cap 440 which isperpendicular to the inner wall surface 435 b.

Finally, the cosmetic liquid L must pass through the fine vent pipe 441located in the center of the sealing cap 440 again in order to bedischarged to the outside.

Therefore, it is practically impossible for such a series of phenomenato occur in succession and the cosmetic liquid L to flow out of thecontainer housing 400.

A cone-shaped protruding end part (442 in FIG. 4 ) protruding from thebottom surface of the sealing cap 440 can contribute to furthercomplicating the outflow path of the cosmetic liquid L.
